GAS-BOILEB.

Speoication of Letters Patent.

Patented Mar. `3, 1914.

Application illed September 30, 1913. Serial N o. 792,642.

To allv lwhom, 'it may concern Be it known that I, CHARLES HOWARD Hoon, a citizen of the United States of America, residing at Pittsburgh, in the countyv -of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in GasfBoilers, of which the provide a compact boiler unit'presenting a large area or surface adapted to be 1mpacted b the iame or products of combustion to o tain the quick heating 0f the water with a minimum expenditure of fuel. t

A further object of the invention is to provide a compact boiler unit, ina manner as hereinafter set forth,fwherein the water circulating therethrough will be .thoroughly heated A further object of the invention is to provide a boilerunit including longitudinal superimposed waterconduits allv of which arer shaped to `bailie and deflect. the heat or products of combustion and to so construct the conduits lwith respect to eachother to provide a bailied pathvfor the passage of the heat or products of combustion.

:Further objects of the invention are to provide a gas boiler which is simple in its construction, and arrangement, strong, ydurable, efficient. and convenient in its use, readilyset up, and comparatively inexpensive to manufact-ure.

.With the foregoing and other objects in view the invention consists of the novel construction, combination and varrangement of parts'as hereinafter vmorespecifically described and illustrated in the' accompanying drawingswherein is shown an embodiment of the inventiombut it isto be understood that changes, .variations and .modicatons scope of the-claims', hereunto appended.

v1n the drawings, whereinhke reference characters.denote 3 corresponding parts thrughoutthe- Several news1-Figure 1 iS ance with this invention, Fig. 2 is a perspective view of one of the boiler units, Fig. 5 1s a sectlon on line X-X, Fig. 2, looking 1n the direction of the arrow, and Fi 4 is a sectlon on line Y-fY, Fig. 2, looklng in the direction of the arrow.

A gas boiler in accordance with this invention includes a plurality of units and as each unit is similar in construction, but one will be described.

Each unit consists of the form illustrated 1n Fig. 2 and includes a pair of hollow vertically disposed end walls 5 6, the latter being formed at its lower end with a tubular offset 7 which communicates with the wall 5 at the lower end, and the former is provided at its upper end with a tubular offset 8 which communicates with the top of the wall 6 by an openingl 9. The end walls 5 6 are connected together at their upper ends by a hollow top wall 10 which provides a steam dome and which has its intermediate portion 11 of less width than its end portions. The end walls '5 6 are mounted at their lower ends upon a gas burner 12, the latter being provided with v outlet ports 13 anda regulating valve 14. When a plurality of units are arranged in proximity in a manner as shown, the tubular offset 8 constitutes a steam or water outlet, while the tubular offset 7 constitutes a water inlet. The water inlet is adapted to be connected to a suitable source of supply, while the steam or .water outlet is connected with the point of consumption. Each unit furthermore includes a series of superimposed water conduits which have their ends connected to the end walls 5 and .6 as well as communicating with the interior of the said end walls.- ACertain of the water conduits are indicated by the yreference character 15 and theother conduits by the reference character 16. Each of the conduits 15 isL what may be termed substantially heart-shaped in cross section, and each ofwhich has each end portion reduced as at 17 whereby the intermediate portion will be of greater area at 17, is of less width than' an end portion.

.The conduits 15-,-16 arealternatelyy 'disposed` with respect ltoeach other and- .the .endav por; tions 'off Vthe.cond1 1itsf :1( 5 are arranged over the reduced end portions o fthe conduits 1.5., .While the-reduced Partielle 1,7?" 'of the conduits 16 are' positioned over the wide intermediateportions of the conduits 15. By this arrangement a circuitous passage is provided for the iame from the gas burner, .or for the heat, or for the products of combustion and the flame is deflected so that it will heat the conduits throughout.

The reduced intermediatel portions of the conduits 16 are connected to the enlarged intermediate portions of the conduits 15 by vertically disposed rectangular pipes 18, whereby communication is established between the central portions of the conduits 15 and the central portions of the conduits 16. The upper conduit l5 which is arranged in proximity to the steam dome, is connected to the latter by a pair ofrectangular-pipes 19, which establish communication between the intermediate portion of the upper conduit 15 and the enlarged end portions of the dome 10. The other conduits 15 haveV their intermediate ortions connected to the end portions o the conduits 16 by a pair of vertically extending rectanlar pipes. 20 whereby communication is established between the end portions of the conduits 16 and the intermediate portions of the conduits l5 other than that conduit 15 which is connected to the steam dome. The pipes 18, 19 and 20 provide what may be termed by-passes between the conduits and between the upper conduit and the steam dome 10. The pipe 18 is twice the area of a pipe 19 or a pipe 20. The combined area of the reduced end portion of a conduit 15 equalsr the area of the reduced intermediate portion of a conduit 16. When a plurality of units are set up, the intermediate portions of the conduits 15 of one unit abut against the intermediate portions of the conduits 15 of the adjacent units and the end portions of the conduits 16 of one unit abut against the end portions of the conduits 16 of adjacent units as clearly illustrated in Fig. 1.

The reference character 21 denotes an inclosing casing for the gas burners 12 as well as a supportlng casing for the units.

22 denotes side plates, and 23 a cover. The side plates are coupled together by the tie bars 24.

The reference character 25 denotes a gas supply pipe for the burners.

An outlet flue 26 is provided for the boiler.

It is apparent that a large Vnumber of units can be readily assembled for use in connection with a large boiler, or for a large hot-water radiating system, or for generating a large amount of steam, or that a single unit can be employed with side plates, whereby the unit can be used in abath room for heating purposes and for heating the water to be used in the bath room.
